To find out how many senior lunches the grant can provide, we will divide the total amount of the grant by the cost per lunch.
The grant amount is \( 1.925 \times 10^6 \) dollars, and the cost per lunch is $2.75.
Now, we can perform the division:
\[ \text{number of lunches} = \frac{1.925 \times 10^6}{2.75} \]
Calculating the division:
- Divide \( 1.925 \) by \( 2.75 \):
\[ 1.925 \div 2.75 \approx 0.700 \]
- Now, we keep the power of 10:
\[ 0.700 \times 10^6 \]
- To express this in proper scientific notation, we adjust it to:
\[ 7.00 \times 10^5 \]
However, since our options do not show \( 7.00 \times 10^5 \), the best option is represented as:
\[ 7 \times 10^5 \]
So, the final answer is:
7×10⁵
